LaPell has your answer -- dryfire practice repeated endlessly will get results! I would only add a couple of things. First,although some get best results from "staging" the trigger slightly, even in rapid fire, I find I get best results by concentrating on a smooth, straight-through pull with absolutely no hesitation. I combine this with complete concentration on keeping the front sight locked on to the target. Lightening the action can be beneficial, but I concentrate on smoothness in the action. Given a choice between smooth and light, I go with smooth every time.
